Advice for new grow please.

Hi all, i am in the process of constructing my grow room. it is 240L X 230H X 150D. i have a 600W cool-star light, but i am unsure of which size RUK fan to buy?
I will be doing either a 6 plant soil or flood&drain for 1st grow.
I will purchase accoustic ducting and carbon filter accordinly.
Air will come in through room and exit out a wall vent.
Any advise much appreciated.
thanks.

make sure to put an air freshner on the extration or you will make a stinking smell

exhaust blower (above 95CFM rating)
two oscillating fans
mylar
HID on chain-link setup so you can keep adjusting the height of the light from the top of the plants
humidifier/de-humidifier
good luck!
